To all whom it may concern.-

Be it known that l, Jenn C. BAncLaY, a citizen of the United States,residing at New York, in the county of New York and State oi 5 New York,have invented certain new and useful Improvements inTelegraph-Transinitters; and I do hereby declare the followi ing to be afull, clear, and exact description of the invention, such as will enableothers to skilled in the art to which it appertains to make and use thesame.

My invention relates to improvements in telegraph-transmitters, andparticularly to improvements in keyboard telegraph-transr5 mitterswherein a series of keys marked according to the various characters tobe trans mitted telegraphically are arranged to operate means wherebywhen each key is operated the correspondin character is transmitted. Theparticular eyboard-transmitter here in illustrated is particularlyintended for use in connection with a page-printing telegraphprintersuch, for example, as illustrated and described in my Patent No.787,608, dated :25 Aprii1'8,1905; butmyinventionisnotlimited to use inconnection with printing-telegraphs or to any'particular code oftransmission, but is applicable for telegraphic transmission generallyand may transmit according to any code desired.

My improved keyboard telegraplntrans mittcr herein illustrated anddescribed comprises a plurality of adjustable steps orcircuitcontroliing devices adjustably mounted in a moving carrier andarranged to be adjusted in position according to the character to betransmitted, so as to represent physio ally that character, and thetransmitter fur ther comprises contact mechanism arranged .o to heopm'ated variably according to the via riable adjustment of said stopsor circuit-con.- trolling; devices, so as to transmit the differentsignals.

lily invention consists in novel and im proved means, as hereinafterdescribed, for operating the transmitting contact mechanism variablyaccording to the character to be transmitted and in many other featuresof invention hereinafter more particularly dco scribed, and pointed outin the claims.

The obj cots of my invention are to improvi-i to huge. I to 5 then-rot,showing the transmitand simplify keyboard telegraph-transmit tors, torender the same certain and rapid in operation, to adapt the some forthe employ ment of approved types of transmitting contact mechanism, toavoid unnecessary delay between characters transmitted, and to make themachine easy to operate, easy to inspect and keep in order, simple,rapid in operation, and relatively inexpensive.

I will proceed to describe my invention with'reference to theaccompanying drawings, which. illustrate two forms of transmittersembodying my invention, in one of which the steps or circuit-controllingdevices are adjusted through. the action of electroniag nets and in theother of which the said. stops are adjusted mechanically, and will thenpoint out the novel features in claims.

in the said drawings, Figure 1 shows a front view oi the transmitterproper of the in agnetically-operated machine sep arate from. itscontrolling-keyboard. Fig. 2 shows a detail side view of the revolvingcarrier and adjustable stops or circuit-controlling devices ofsaidtransmitter, part of the stops being omitted. Fig. 3 shows a sideview and partial section of such transmitter proper detached from itskeyboard, only one of the stops and only two of the adjusting-magnetsbeing shown. Fig. 4 shows a detail end view of the locking-disk andassociated parts of said transmitter. Fig. 5 shows a detail sectionthrough the clutch of said transmitter. Fig. 6 shows a side view andpartial section of one form of keyboard which may be employed in mytransmitter. Fig. 7 is a diagram showing the electrical connections ofmy transmitter shown in Figs. 1 to 6, inclusive. Fig. 8 shows a top viewof the key board shown in Fig. 6. Fig. 9 is a view similar to Fig. 3 ofthe mechanically-operated transmitter wherein there are directmechanical connections between the key-levers and the pusher-s whichadjust the stops or circuitcontrolling devices. Fig. 10 shows a frontview of said. mechanically-operated transmitter. Fig. 11 shows a topview of the key boardof said lnechanically-operated transmittcr, theother portions of the instrument having beenrenioved. Fig-5.12 and. 13are detail side views of the drum or carrier 1, illustrating alternativearrangements of the stops.

Referring now to the drawings and at first tor proper, numeral lindicates a revoluble drum or corner prd'ded near its periphery slumwith a circular row or series of adjustable stops or circuit controllingdevices 2, arranged longitudinally and each. surrounded by a lightspiral spring 3, the only function of which is .to retard slightly byfriction longitudinal motion of the stop, Said stops are longitudinallymovable with respect to the drum 1, and normally they project slightlyat the front of the drum, their rear ends being substantially flush withthe rear surface of the drum. By means hereinafter described as many asdesired of these stops may be pressed in or back to constitute aphysical reproduction of each character to be transmitted. Fingerscontrolling the operation of the transmitting contact mechanism arepermitted to or prevented from o crating, according to the adjustment oft. ese stops, as hereinafter described. Drum 1 is arranged to berotated, being mounted upon a shaft 4, arranged to be driven through aclutch 5 by a gear-wheel 6. Any suitable means may be employed fordriving gear 6, such as an electric motor, a weight, a spring, &c. I donot illustrate and do not limit myself to any particular type of motorfor the purpose.

The contact mechanism for transmitting the signals which I prefer to useis similar to that of the well-known Wheatstone automatic transmitter,but is not controlled by a perforated tape, as in the Wheatstoneinstrument, the drum 1 and its stops serving in lieu of a perforatedtape. Said contact mechanism (shown particularly in Figs. 1' and 3)comprises a pivoted contact-arm 7, pivoted at 8 and arranged to makecontact alternately with stops 9 and 10. These stops and the centralpivot 8 constitute circuit-terminals, and these circuit-terminals, withthe contactarm 7,will be recognized as constituting a familiararrangement of contact-points com-- monly employed in polar transmittersused with dynamo-currents. For vibrating the pivoted arm 7 bell-cranks11 and 13, connected by adjustable links 12 and 14 to opposite sides ofarm 7, are provided. Links 12 and 1 1 have sliding connections withcontact-.

arm 7, ivory bushings 12 and 1 1 on these links sliding freely throughbearing-orifices in said arm, thus permitting some lost motion. Springs15 act upon the bell-cranks, tending to cause each bell-crank to movethe contact-arm 7 toward the corresponding contact-stop 9 or 10. Motionof the bell-cranks is produced, however, by the action of a vibratingrocker 16, arranged to be rocked by a link 17 and crank 18, the latterdriven by suitable gearing 19 from shaft 4. Said rocker carries pins orfingers 20 and 21, engaging arms of the bell-cranks 11 and 13, as shown,the rate of oscillation of rocker 16 being the same as the rate ofpassage of the stops 2 past a given point during the rotation of drum 1.

Each time the right-hand end of rocker 16 rises spring 1 tends to causebell-crank 11 states and link 12 to move contact-arm 7 into contact withstop 9, and each time the left-hand end of rocker 16 rises spring 15tends to cause bell-crank 1.3 to move contact-arm7into contact'with stop10. The movement of the bellcranks and contact-arms 7 is determined bythe adjustment of the stops 2 through the agency of pins 22 and 23,carried by bell cranks 11 and 13, respectively, and guided so as to movesubstantially vertically. Pin 22 is just beneath the ends of stops 2 asthey project in their normal positions from the front of drum 1, and pin23 is just beneath the rear ends of stops 2 when said stops project atthe rear, owing to being pushed in from the front. In the normaladjustment of stops 2, in which said stops all project to the front,pin22 can not rise materially during the reciprocation of the rocker 16,upward movement of said pin being prevented by the projecting ends ofstops 2, and therefore contact-arm 7 is stationary, normally in theposition indicated in Fig. 1, in contact with stop 10 but when, as pin22 starts to rise, the stop 2 opposite the end of such pin at thatinstant has been pressed in, said pin 22 continues to rise, causing thecontact-arm, 7 to shift-into contact with stop 9, so initiating asignal. Said signal will be short or longi. 6., will be a dot or adashaccording as one or a plurality of ad-' jacent stops 2 have beenpressed in. If only one stop has been pressed in, then when rockerarm 16causes pin 22 to move dovmward upward motion of pin 23 will not beblocked through the projection of the end of the next adjacent stop 2from the rear of drum 1, and.

pin 23 will rise, moving contact-arm 7 back into contact with sto 10 andterminating the signal, which wil thus be of minimum lengthviz., a dot;but if, say, three adja' cent stops 2 have been pressed in at its firstattempt pin 23 will be prevented from rising by the projecting rear endof the second of the stopsso pressed in, and it will not be until thefourth stop, counting from the first stop pressed in, is opposite pin 23that the latter can rise and reverse the position of contact arm 7. Itwill be obvious, therefore, that when three adjacent stops are pressedin the contact-arm 7 remains in contact with stop 9 longer than whenonly one stop is pressed in. Similarly, if five adjacent stops arepressed in a still longer signal will result.

It is not essential that a single stop 2 pressed in shall represent adot and three stops pressed in shall represent a dash. A plural-V ity ofstops-as, for example, threemay be employed to transmit a dot and astill higher number a dash, and the dashes and the intervals between thedots and dashes may be of varying lengths. It will be noted that thestops 2 when adjusted to produce the dots an dashes of a character of atelegraphic code in effect constitute a physical represen tation of thatcharacter.

ti. near it jockey 26 tends to hold contact-arm i in either of itsextreme positions, and so over comes the tendency of the friction ofbushings 12 and 14 when sliding through the contact-arm to shift saidarm impro erly.

The drum 1 is shown as rovi ed with more stops or circuit-controlingdevices 2 than will be required for any one character of any of thetelegraph codes commonly used. All oi'" the stops required for any onetelegraph character are adjusted simultaneously either byelectromagnetic means, as illustrated in Figs. 1 and 3, or by mechanicalmeans directly actuated by the key-levers, as illustrated in Figs. 9 and10, and while the stops are being adjusted in position to make thedesired character the rotation oi the drum 1 is stopped momentarilythrough the opening of the clutch 5 and the operation of locking meanshereinafter described. As soon as the adjustment of the steps iscomplete the rotation of the drum 1 begins again, and as the stops oithe character to be transmitted pass the pins 22 and 23 they control theupward movement 01 said pins and the oscillation of the contact-arm 7 insuch manner as to cause the transmission of the character represented bythe adjustment of the stops. After each stop passes the pins 22 and itencounters a resetting-cam 27, by which all of the stops which have beenpressed in or back are pressed out again and are thus prepared to beadjusted for another character.

The means for adjusting or setting the stops 2 for the character to betransmitted (illustrated in Figs. 1 and 3) comprises mag nets 28,arranged in two series in arcs of circlcs about the drum 1. and providedwith armature-levers 29, arranged to actuate pushpins 30, suitablyguided and arranged in the are of a circle opposite the ends of stopsZ.In the arrangement shown there are sixteen such magnets 28; but thisnumber may be less orgreater, according to the demands of thetelegraphic code used. Suitable compression-springs 31 move back thearmaturelevers and push-pins 30 when their magnets are deenergized. Thecircuits of these magnets 28 are controlled by corresponding contacts ofa keyboard. Figs. 6 and 8 illustrate one keyboard comprisingfinger-keys, contacts, and selecting mechanism determining whichcontacts are closed by the depression of the several keys. This keyboardmechanism, however, is only one of many which I mayemploy, and l do'riotlimit myself to the use of the particular mechanism illustrated. Saidkeyboard mechan sm--comprises a plurality oi finger-keys 3], carriedeach by a corresponding key-lever 32, and the iingen keys may be markedthe same as the keys of a type-Writer, each with the particular letteror character to which it corresponds. in fact, keys 31 and key levers 32may be the keys and keylevers of a type-writer, being provided. withconi'iections, such as 33, for operating the printing and othermechanism of a type-writer in the ordinary manner. I do not illustratethe mechanism of any typewriter other than the keys, keyleve rs, andconnections 33, as such mechanism forms no portion of my invention, andthe selecting mechanism herein illustrated and described may be operatedin the manner illustrated b the key-levers of most, if not all, of thewel known ty e-writers.

Beneath the key-levers 32 are a plurality of contact-operating levers orbails 34, pivoted at 35, and the key-levers are prowided with aplurality of notches 36, corresponding in position to the bails 34,which said key-levers are not to actuate when deressed. Each key-leveris notched dii'lerent y from all of the others, and therefore eachkey-lever when depressed actuates a characteristic combination ofbails'34, and so energizes a characteristic combination ofadjusting-magnets 28 and produces a characteristic adj ustment of stops2, constituting the combination oi dots, dashes, spaces, &c., which makeup the corresponding telegraphic character.

The particular type of'contacts operated by the bails 34, illustrated inthe drawings and which is only one of many which may be employed,consists of a projection 37, carried by the corresponding bail andarranged when it is raised by the depression of said bail to lift aspring contact-tongue 38 into contact with a contact-point 39.

In order to prevent premature actuation of the magnets 28, the circuitsof said magnets are controlled by a master-contact closed by thedepression of the finger-key after the Various selecting contacts haveall been closed. The master-contact is exactly similar, except as toadjustment, to the several selecting contacts 37 38 39 and is operatedby a bail 41, similar tothe selecting bails 34, which all oi" thekey-levers actuate when depressed.

For operating the clutch 5, through which the drum 1 is driven, a magnet42, Fig. 3, is provided. The armature 43 of this i'nagnet is connectedby a link 44 to a bellcrank lever 45, which actuates the sliding member46 of the jaw-clutch 5, which member is splined to its shaft. The othermember d7 of the clutch is in permanent drivin cormection with themaindrivingear 6. Vhen the magnet 42 is energized, t e clutch is opened,and, con verscly, when the magnet is dei nergised the clutchis closed bythe acti n of spring 4.8.

To arrest the drum 1 promptly and in the pro or position, a locking disktil, Fast to shat 4, is provided, and lever is provided with a tooth 50,arranged when said lever is depressed to open the clutch to enter one ofthe various notches in said lockingalisk and arrest and center thedrum 1. To aid in bringing the drum 1 to rest inproper position and toinsure that it shall remain steady run tilshaft 4 is released andtheclutch 5 closed,

I further provide a friction-drag consisting of a fianged disk 51,driven by gear 6, and a spring 52 within the flange of said disk, one

s 'end of said spring secured to shaft 4, the

other carrying a pad 53, which is pressed by said spring against theflange of disk 51.

The armature 43 of the clutch-ma net 42 carries a contact-spring 54,adapts when to said armature is attracted to ma e contact with a stop55. This contact 54 55 controls the circuits of the adjusting-magnets28, as hereinafter described.

Sprin s 56 and 57 are provided for return- 1 ing the icy-levers 32 andselecting-bails 34 when released after being depresse When my improvedtransmitter is to be used in connectlon with printing-telegraphs of thepage-printing type, I employ means for indicating when the end of theline is approached, so that the transmitting operator may operate therelease or carriage-return key at the proper time. The indicating meansfor this pur ose (illustrated in the drawings) consists o awheel 58,upon the periphery of which may be any suitable scale or marks toindicate the position of the carriafie of the receiving-printer and amark to 1n cate the end of the line. This Wheel is 0' rotated by aratchetwheel- 59, connected to it and arranged to be rotated step bystep as the keys are operated successively by a ratchet 60, operated b auniversal bar 61, which is beneath the ey-levers "and is de- 3 5 pressedby each such lever when the latter is actuated. A locking-disk 62,likewise driven with the ratchet-wheel, is provided with a notch 63,which a locking-lever 64 enters when the end of the line is reached,thereby d locking thekeys, for since the ratchet-wheel 59 cannot movewhen the disk 62 is so locked, neither can the ratchet 60 and theuniversal bar' 61, and the latter holds the key-levers from beingdepressed.

The return of the carriage of the receivingprinter is accomplished bythe depression of a key marked Release in the representation of thekeyboard, Fig. 8, Such key is arranged when depressed to operate a cone5o sponding combination of selecting-bails 34,

which will cause the transmission of a characteristic signal by whichappropriate mechanism of the printer will be operated and thereturn ofthe carriage of the printer accomplished. This release-key is providedwith a projection 65, Fig. 6, which encounters a lever 67 and pressesitaside before said releasekey, or, more properly, the key-leverthereof, encounters the universal bar 61. The lever 6o 67 when sopressed aside operates locking-lever 64 through a link 68, releasing thedisk 62, and then the release-key lever, encountering the universal bar61, depresses the same,

tooth to the mark corresponding to the be- 65 ginning of the line.

In case the keyboard of my transmitter is the keyboard of a type-writerthe indicating mechanism above described may be omitted, as the carriageof the type-writer and the indicator customarily provided in connectiontherewith serves the same purpose as the disk 62.

Referring now to the diagram Fig. 7, said diagram shows one key-lever 32and beneath it the various selecting contacts 38 39, which are operatedby the depression of the key-levers, together with the master-contact,which is operated by all of the key-levers. Said diagram also showsbeneath the selecting contacts the corresponding adjusting-magnets 28,and beneath said magnets is shown in partial perspective a diagrammaticdevelopment of the drum or carrier 1, (which by development becomes abar,) together with a number of the stops or circuit-controlling devices2 carried thereby. The diagram further shows the clutch or stop-magnet12 and the contact 54 55 operated thereby. As shown, the circuit of thisclutchsmagnet is closed by the closing of master-contact 40, and saidclutch-magnet when its circuit is closed closes contact 54 55,and thereboperates a relay 69, controlling the circuits of the adjusting magnets28. The armature of said relay 69 has a T-head 70 and contactsprings 71and '7 2, arranged to make contact with steps 73 and 73*, respectively.Normallyspring 71 and stop 73 are in contact and spring 72 and stop 73*- are out of contact but soon after the armature of relay 69 whenattracted begins to move contact is closed between 72 and 73*, therebyclosing circuit through the selecting contacts 38 39, which have beenclosed by the depression of the particular key-lever actuated, andthrough the corresponding adjusting-magnets 28. Before the armature ofrelay 69 has ended its movement contact between 71 and 73 is broken bythe T-head 7 O, pulling spring 71 away from stop 73, and theadjusting-magnets 28 are thereby deenergized. This is done in order thatthe push-pins 30, actuated by said magnets, may have cleared the ends oithe stops 2, which have not been pushed in, before the carrier 1 beginsto rotate again. As will be seen, said push-pins are not pushed in toadjust the stops 2 until the stop-magnet 42 has opened the clutch 5, forit is not until said stopnnagnet has operated that relay 69 operates.Therefore there can be no conflict between pins 30 and stops 2 when saidpins are pressed in; but since stop-magnet 42 is deenergized the instantthe finger-key which has been depressed is released and since thedepression of said finger-key may continue for only a very brief instantand as soon as moving the indicating-wheel 58 forwardone 1 said key isreleased the clutch 5 closes and ation will have completed the circuitthrough the selected adjusting-magnets and then broken said circuitagain before the do ression of the finger-key is completed, the riottime during which the selecting-circuit is completed being neverthelesssufficient for the operation of the adjusting mechanism.

The operation of the transmitter shown in Figs. 1 to 8,inclusive, (theelectrical or electromagnetic form of the transmitter,) is as follows:When one of thefinger-keys is depressed, it depresses a correspondingcombination of selecting-bails 34 and operates the corres endingselecting-contacts 38 39, and also c oses master-contact 40', at thesame time moving the indicating-wheel 58 one s ace. The master-contact40, when comp eted, closes circuit through the clutch or stop magnet 42,thereby opening clutch 5 and arresting the motion of the carrier 1, andthen closes circuit through contacts 54 55 and the relay 69, thusoperating said relay and causing the same to close circuit momentarilthrou h the selecting-contacts 38 39, which have con closed, and throughthe corresponding adjusting-magnets. Said magnets being thus ener izedattract their armatures, movin forwar the corresponding push-pins 30 anpushing in the stops 2 o osite the ends of said pins at the instant. T eadjusting-magnets are then denergized and the push-pins are drawn backclear of the ends of the stops 2, which have not been pushed in. As soonas the finger-key which has been depressed is released mastercontact .40is roken, the sto -magnet 42 is denergized, the clutch 5 is c osed, andthe drum 1 begins to rotate, the rocker 16, Figs. 1 and 3, of thetransmitting-contact mechanism at the same time beginnm to vibrate. Assoon as, during an upwar movement of the ri ht-hand end of said rocker(as viewed in ig. 1) a stop 2, which has been pressed in, comes oppositethe controllin -pin 22 of the transmitting-contact mec anism said pin ispermitted to rise, thus reversing contact-arm 7, closing contact at 9,and imtiating a signal. During the'next succeeding downward movement ofthe right-hand end of rocker 16 in 22 will be depressed clear of thestops, an if the next succeeding stop has not been pressed .incontrolling-pin 23 will be permitted to rise, reversing co tact-arm 7,closing contact at 10, and terminating the sign al, which in such caseis a dot; but if three s acent stops 2 have been pressed in pin 23 willnot be permitted to rise, and the signal will continue until the fourthstop or any succeeding evennumbered stop (counting from that firstmentioned) which has not been pressed in comes opposite said pin 23,whereupon said pin will rise and the contact-arm7 will be moved intocontact with sto (which in such case wil be a dash) will be terminated.As the drum .rotates the ends of the stops which have been pushed inencounter the inclined surface of the resetting-cam 27 and are pressedback successively to their -first position.

It will be seen that by pressing in various combinations of the stops 2I may cause the transmitting-contact mechanism to produce variouscombinations of dots, dashes, and s aces, as required bytelegraph-codes, and that these dots, dashes, and spaces may be ofvarious lengths. It will be seen, further, that the transmitter iscapable of extremely rapid operation. I do not limit myself to anylparticular type of transmitting-contact mec an- 10, and the signal ismnor to transmitting mechanism of the pole-changing type; but I prefertouse con tact mechanism, whether circuit-breaking or pole-chan ing, ofthe general type illustrated, which has een thoroughly trie out inactual practice and is well known to be durable and ca able of greatspeed.

11 order to overcome the effects of foreign currents on the line,earth-currents, &c., I preferably do not connect the transmitti contactmechanism above described direct y to the line, but cause it to operatea relay 7 4, as shown in Fig. 7, said relay being connected the signalsof the transmitting-contact mechanism, and having means for iving a biasto one side over the other, 8110 giving of bias is customarilyaccomplished by mounting the stops of the relay upon a plate, as 75,formed of msulatin material or otherwise arranged to insulate t e stopsfrom each other and provided with means-as, for example, a worm 7 6-formoving the plate to one side or the other, so that in one extremeposition the armature will be nearer its magnet-pole than in theopposite position.

Instead of employin electrical means, as above described, for a justingthe positions of the stops I may employ mechanical means for thatpurpose. Figs. 9, 10, and 11 illustrate such a transmitter. The generalconstruction of the instrument is the same as that of theelectrically-operated instrument above described, and Where ossible thesame reference-numerals are emp oyed. The'construction of the drum 1 andthe means by which it is driven are the same as above described;likewise the transmitting-contact mechanism and the general structure ofthe keyboard. The selecting-bails of this key board instead of operatincontacts, as in the electrical form of transmitter, are connected bylinks 77 to hell-cranks 78. The upper arms of these bellcranks arecurved, as shown in Fig. 10, so that their ends are in an to the line asshown, so as to repeat therein ISO are of a circle approximatelyconcentric with the axis of drum 1, and these ends are connected to thepush-pins, by which the stops 2 actuating the clutch 5 and the lockingdevice of the carrier 1 a master-bail 79, corresponding to bail 41 ofFig. 6, is provided. This bail actuates a lever 80, which has a yieldingconnection, through a spring 81, witha bellcrank 82, connected by link44 with the clutchoperating'and lock-operating lever45'. The

effect of the elastic connection formed by the spring 81 is that as soonas a key-lever is depressed, and with it the bail 79, thespring 81,which is of sufficient stifiness to overcome the clutch-spring 48,communicates motion to lever 82 and clutch-and-lock lever 45, openingthe clutch and stopping the drum 1. This occurs before any of theselecting-bails 34 have been depressed. As

said key-lever is depressed further the'appropriate selecting-bails 34are depressed (the spring 81 compressing to permit further motion of thekey-lever after locking tooth 50 has reached the limit'of its movement)and the corresponding push-pins 30 are pressed in, pressing in thecorresponding stops 2. When the finger-key is released, the push-pins 30are first withdrawn and then the lever 82 is permitted to rise, thetooth 5O clearing the ocking-disk 49 and the clutch 5 closing.

It is obvious that the mechanical means shown for adjusting the stops 2by the action of key-levers is only one of many mechanisms which may beused for the purpose, and I do not limit myself to the particularmechanism shown.

Instead of causing the controlling fingers or pins 22 and 23 of thetransmitting-contact mechanism to coact with the ends of'the stops 2 Imay employ stops, as shown in'Fig. 12, having grooves 83, which whenopposite the end 0 a pin 22 or 23' permit that pin to rise sufficientlyto operate the transmittingcontact mechanism, or, as illustrated'in Fig.13, I may provide the stops with lugs 84, which wheno posite a pin 22 or23 will prevent that pini i that still other ways of controlling therise of the pins 22 and 23 by meansof'the adjustable stops maybeemployed.

It will be obvious that my improved keyboard-telegraph transmitterherein illustrated and described is susceptible of many variations andmodifications'without departing from the spirit and scope of myinvention, and, further, that certain parts may be used in connectionwith other parts of differ entconstruction. I do not limit myself,therefore, to the particular details of conom rising. It will be obviousstruction, arrangement, and operation herein illustrated and described.
